摘要： A 2-D scanning system uses a fast-rotating raster-polygon as a single scanning component to produce straight scan lines over a 2-D image surface. An approach angle of incident light beams to the raster-polygon is selected to minimize pin-cushion distortion of scan lines introduced by polygon scanning on the image surface, and a tilt angle of the rotational axis of the raster-polygon is selected to position said polygon-scanning distortion symmetrically on the image surface. In addition, scan optics are configured to generate a predetermined amount of barrel distortion of scan lines on the image surface to compensate for pin-cushion distortion introduced by polygon scanning.

摘要： In an apparatus for displaying the picture information of an incoming interlaced television signal in noninterlaced raster scanning display on the faceplate of a picture tube, each video line of the television signal is separated into R, G and B color component signals. Each video line is compressed, or speeded-up, at a variable rate and delayed by a variable delay time to provide a speeded-up signal that is coupled to the corresponding electron beam gun of the picture tube. Each of the variable rate and delay is controlled in accordance with information relating to distortions of the raster scanning display. In this way, distortion, such as east-west or convergence, is reduced when the speeded-up signal is displayed.

摘要： PURPOSE:To reduce ringing of a horizontal deflection current caused by the insertion of a linearity coil by adding a circuit where a resistor and a switching element are combined in parallel with the linearity coil. CONSTITUTION:A diode 15 is connected in series with a resistor 14 to block a current flowing to the resistor 14 at the blanking period. Since a capacitor 16 is connected in parallel with a stray capacitance 13 across the linearity coil 6, the ringing frequency is changed by changing the capacitance of the capacitor 16. Then the effect making a curtain stripe of a pattern more unremarkable is obtained by selecting the capacitance of the capacitor 16 to nearly 470pF.
